IMAGE PROCESSING METHOD, IMAGE PROCESSING DEVICE, IMAGE FORMING DEVICE, AND INKJET RECORDING DEVICE

摘要

An image processing method according to one mode of the present invention includes: applying mask processing to an abnormal recording element based on abnormal recording element information (10); converting input image data (14) such that a pixel to be formed by the abnormal recording element is excluded; applying quantization processing that converts the converted input image data (16) to image data having a gradation number less than a gradation number of the converted input image data; and assigning each pixel forming image data after quantization processing to a normal recording element.
